Overview#
IEC/TC 111 is the committee that writes the environmental rulebooks for electronics. These are the standards that tell the industry how to declare materials, test for restricted substances, and document compliance.
The committee behind IEC 62474 (material declaration and the DSL), IEC 62321 (substance testing) and EN IEC 63000 (RoHS technical documentation).
What it does#
IEC Technical Committee 111 handles environmental standardization for electrical and electronic products and systems. Its output underpins how companies meet regulations like RoHS and REACH.
Key standards it maintains#
- IEC 62474: the material declaration format and the maintained Declarable Substance List.
- IEC 62321: methods for the determination (lab measurement) of restricted substances in electrotechnical products.
- IEC 63000: technical documentation for assessing EEE against substance restrictions, the harmonized route for RoHS technical files.
- Emerging work such as IEC 82474-1.
Why it matters#
When a standard referenced by a regulation is updated, it changes what evidence and data formats you need. Tracking TC 111 tells you where electronics environmental compliance is heading.
